Could it be the checksum error?

 

User Datagram Protocol, Src Port: 41486 (41486), Dst Port: tftp (69)
    Source port: 41486 (41486)
    Destination port: tftp (69)
    Length: 13
    Checksum: 0x3333 [incorrect, should be 0x419b (maybe caused by "UDP checksum offload"?)]
        [Good Checksum: False]
        [Bad Checksum: True]
Trivial File Transfer Protocol
    Opcode: Unknown (28777)
    Data (3 bytes)
